The SIWOH1 (GLR) series isolation switch fuse group (hereinafter referred to as the switch) is a multi-pole, manually operated switch made of unsaturated polyester glass fiber reinforced plastic (DMC) and manufactured with a shell, which has high dielectric performance, protective ability, and reliable operational safety.
The operating mechanism is a spring energy storage, instantaneous release acceleration mechanism, and a multi break point contact structure that momentarily connects and disconnects. It is independent of the speed of the operating handle and improves various electrical and mechanical properties.
The isolation switch fuse group can ensure the on-load connection and disconnection of circuits, and is equipped with a fuse link for reliable overcurrent or short circuit safety breaking protection.
Has strong resistance to moisture and heat.
